Kerry says he wants to have talks with Iran and North Korea to prevent/remove their nuclear programs, right? I believe he said bilateral talks with Korea (perhaps he wants to buy them off like Clinton did), and talked about making an offer to buy back nuclear materials from Iran, right??
What did Europe do during the early 30s to appease Hitler's Germany?? That's right, they talked and negotiated, eventually giving Germany back the Sudenland of Czechoslovakia(sp?) and the Rhineland.
Am I saying talks are bad? Not at all, but you cannot simply hope that appeasing a dictator will make them go away.
Hitler took what he was given, then went after the rest of Europe.
Iran will likely go after Israel (or worse, give the nukes to terrorists).
N. Korea, once it has food and money from us, will likely still continue its weapons and attack South Korea and/or Japan.
